MAX154AENG+ Equivalent & Substitute Parts

Part Overview

The MAX154AENG+ is an 8-bit analog-to-digital converter with 4 single-ended inputs, integrated multiplexer, sample-and-hold circuit, and internal reference. This device is classified as obsolete and operates on 5V supply for both analog and digital domains. Given its obsolete status, identifying functionally equivalent alternatives is essential for system redesign, long-term production planning, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX154AENG+ is determined by strict equivalence across the following critical parameters:

• Resolution: 8-bit conversion capability
• Channel Count: 4 single-ended input channels
• Sampling Rate: 400 kSPS minimum
• Architecture: Flash ADC topology
• Reference: Internal voltage reference
• Supply Voltage: 5V analog and digital supplies
• Data Interface: Parallel output
• Package: 24-DIP form factor for through-hole mounting
• Temperature Range: -40°C to 85°C operation

Based on the provided input data, the MAX154AENG+ is listed as its own direct equivalent. No additional substitute parts are specified in the input parameters.

Parameter Comparison

Engineering Selection Recommendations

The MAX154AENG+ is an obsolete component. When sourcing replacements, prioritize parts that maintain identical electrical specifications: 8-bit resolution, 4-channel single-ended input, 400 kSPS sampling rate, flash architecture, internal reference, and 5V dual supply operation. The 24-DIP through-hole package is a critical mechanical constraint for board-level compatibility.

Current inventory availability of 975 pieces may support near-term production needs. For long-term supply assurance, evaluate modern ADC alternatives from Analog Devices or equivalent manufacturers that offer the same functional specification in contemporary packaging options such as SOIC or QFP, if board redesign is feasible.

Compliance with ROHS3 and EAR99 export classification should be maintained in any substitute selection.

Frequently Asked Questions (FAQ)

Q: Why is the MAX154AENG+ considered obsolete? A: The MAX154AENG+ is classified as obsolete by the manufacturer, indicating it is no longer in active production. This status necessitates proactive sourcing strategies and evaluation of alternative components for future designs.

Q: What defines a valid substitute for the MAX154AENG+? A: A valid substitute must match all critical parameters: 8-bit resolution, 4 single-ended input channels, 400 kSPS sampling rate, flash architecture, internal reference, 5V analog and digital supply, parallel data interface, and -40°C to 85°C operating temperature range.

Q: Can the MAX154AENG+ be replaced with a different package type? A: Package substitution is not recommended without board redesign. The 24-DIP through-hole form factor is mechanically specific. Alternative packages require PCB layout modifications and may introduce compatibility issues.

Q: Is the MAX154AENG+ RoHS compliant? A: Yes, the MAX154AENG+ is ROHS3 compliant, meeting current environmental and hazardous substance restrictions.

Q: What is the current inventory status? A: 975 pieces of new original MAX154AENG+ are currently in stock as bulk inventory.
